"It's the Georgian velvet revolution!" proclaimed jubilant radical opposition leader Mikhail Saakashvili as he and hundreds of cheering supporters burst into Tbilisi's parliament Saturday afternoon. By nightfall, the country was in chaos, its leadership uncertain, its territorial integrity threatened and there were still some fears that the velvet might become stained with blood. The legislative body, elected in Nov 2. polls that were marred by charges of widespread vote rigging, had been ordered into session by President Eduard Shevardnadze, but only 114 of the 235 deputies had bothered to show up.
